Description
FIELD
[0001] The present application is related to a light bulb and more
particularly related to a LED light bulb with wide angle
illumination.
BACKGROUND
[0002] Electroluminescence, an optical and electrical phenomenon,
was discover in 1907. Electroluminescence refers the process when a
material emits light when a passage of an electric field or current
occurs. LED stands for light-emitting diode. The very first LED was
reported being created in 1927by a Russian inventor. During
decades' development, the first practical LED was found in 1961,
and was issued patent by the U.S. patent office in 1962. In the
second half of 1962, the first commercial LED product emitting
low-intensity infrared light was introduced. The first
visible-spectrum LED, which limited to red, was then developed in
1962.
[0003] After the invention of LEDs, the neon indicator and
incandescent lamps are gradually replaced. However, the cost of
initial commercial LEDs was extremely high, making them rare to be
applied for practical use. Also, LEDs only illuminated red light at
early stage. The brightness of the light only could be used as
indicator for it was too dark to illuminate an area. Unlike modern
LEDs which are bound in transparent plastic cases, LEDs in early
stage were packed in metal cases.
[0004] With high light output, LEDs are available across the
visible, infrared wavelengths, and ultraviolet lighting fixtures.
Recently, there is a high-output white light LED. And this kind of
high-output white light LEDs are suitable for room and outdoor area
lighting. Having led to new displays and sensors, LEDs are now be
used in advertising, traffic signals, medical devices, camera
flashes, lighted wallpaper, aviation lighting, horticultural grow
lights, and automotive headlamps. Also, they are used in cellphones
to show messages.
[0005] A Fluorescent lamp refers to a gas-discharge lamps. The
invention of fluorescent lamps, which are also called fluorescent
tubes, can be traced back to hundreds of years ago. Being invented
by Thomas Edison in 1896, fluorescent lamps used calcium tungstate
as the substance to fluoresce then. In 1939, they were firstly
introduced to the market as commercial products with variety of
types.
[0006] In a fluorescent lamp tube, there is a mix of mercury vapor,
xenon, argon, and neon, or krypton. A fluorescent coating coats on
the inner wall of the lamp. The fluorescent coating is made of
blends of rare-earth phosphor and metallic salts. Normally, the
electrodes of the lamp comprise coiled tungsten. The electrodes are
also coated with strontium, calcium oxides and barium. An internal
opaque reflector can be found in some fluorescent lamps. Normally,
the shape of the light tubes is straight. Sometimes, the light
tubes are made circle for special usages. Also, u-shaped tubes are
seen to provide light for more compact areas.
[0007] Because there is mercury in fluorescent lamps, it is likely
that the mercury contaminates the environment after the lamps are
broken. Electromagnetic ballasts in fluorescent lamps are capable
of producing buzzing mouse. Radio frequency interference is likely
to be made by old fluorescent lamps. The operation of fluorescent
lamps requires specific temperature, which is best around room
temperature. If the lamps are placed in places with too low or high
temperature, the efficacy of the lamps decreases.
[0008] In real lighting device design, details are critical no
matter how small they appear. For example, to fix two components
together conveniently usually brings large technical effect in the
field of light device particularly when any such design involves a
very large number of products to be sold around the world.

is used for supplying electricity to the LED light filament 21. The
bracket 22 is made of hard material. Thus, the wire is used for
electrical connection.
[0128] In the example, the amount of the lever 26 is two. The two
lever 26 are disposed in a gap.
[0129] The amount of the lever 26 is also acceptable for more or
less than two.
[0130] Please refer to FIG. 1 to FIG. 3. The filament bulb 100 is
an embodiment. The support 25 is made of earthenware or hard
material in order to avoid the risk of breaking. In some examples,
a production of the support 25 takes less time. The support 25 is
made of glass. The glass support 25 is used for connecting a bulb
12. When the support 25 is made of earthenware or hard material
while the bulb 12 is made of plastic or glass. The bulb 12 is used
for connecting the support 25.
[0131] Please refer to FIG. 1 to FIG. 3. The filament bulb 100 is
an embodiment. The support 25 includes a trumpet segment 251 and a
support segment 252. A wide narrow end of the trumpet segment 251
is connected to the support segment 252. A diameter end of the
trumpet 251 is connected to the bulb 12. The lever 26 is fixed on
the support segment 252.
[0132] The trumpet segment 251 is used for connecting the support
25. The support 25 is used for connecting the bulb head 11
steadily. The support segment 252 is used for supporting the lever
26.
[0133] Moreover, with respect to the support 25, the lever 26 is on
a tilt. The lever 26 supports the bracket 22 and adjusts the tilt
angle of the LED light filament 21.
[0134] Please refer to the FIG. 1 to FIG. 3. The filament bulb 100
is an embodiment.
[0135] An exhaust tube 253 is disposed in the support segment 252.
A gas hole 254 of the support segment 252 is connected to the
exhaust tube 253. The gas hole 254 is used for exhaling the gas of
the bulb 12. Moreover, some heat conductive airs are filled into
the bulb 12 for heat dissipation.
[0136] The diameter end of the trumpet segment 251 is used for
connecting the bulb 12 while processing. The exhaust tube 253 is
disposed in the support segment 252. The exhaust tube 253 exhales
the gas and fills the heat conductive airs into the bulb 12.
[0137] The exhaust tube is sealed in order to avoid an air
leakage.
[0138] In other examples, the central column 24 is longer. Thus,
the exhaust tube 253 is disposed in the central column 24
directly.
[0139] Moreover, the support segment 252 is a cellular structure.
The exhaust 253 is disposed in the support segment 252.
[0140] The cellular structure is used for disposing a wire in the
support segment 252. The cellular structure is connected
electrically to the LED light filament.
[0141] In other examples, the support segment 252 is a cellular
structure. The tube hole is the exhaust tube 253.
[0142] Please refer to FIG. 1 to FIG. 3. The filament bulb 100 is
an embodiment.
[0143] The bracket 22 includes multiple extending levers 221. Each
extending lever 221 is disposed on the central column 24.
[0144] The extending lever 221 is used for connecting and
supporting the LED light filament 21. Specifically, in the example,
each extending lever 221 is connected to the lever 26.
[0145] A length of each bracket 22 is bent in half. The bending
makes the extending lever 221 into four pieces.
[0146] In other examples, the amount of the extending lever 221 is
acceptable for more than two.
[0147] An end of each extending lever 221 is connected to the
central column 24 directly. In other examples, the end of each
extending lever 221 is used for disposing a supportive structure.
The end of each extending lever 221 is used for connecting each
extending lever 221.The end of each extending lever 221 is used for
connecting the supportive structure and the central column 24. The
supportive structure has multiple kinds of forms, such as a
circular, a ring or a torus etc.
[0148] Please refer to FIG. 4. The filament bulb 100 is an
embodiment. The bracket 22 also includes multiple support rings
222. The support rings 222 are used for supporting the extending
lever 221. The support rings 222 are disposed on the lever 26. The
extending lever 221 is extended from the support ring 222. The
support ring 222 is disposed for supporting the extending lever 221
and connecting the central column 24. The extending lever 221 is
connected and disposed to the central column 24.
[0149] Moreover, an one-piece forming is formed by the support ring
222 and each extending lever 221.
[0150] Moreover, in the example, the amount of the extending levers
221 is six. The extending levers 221 are equally disposed in the
circumferential direction of the support ring 222.
